SULKYI-PLOW.

SPECIFICATION forming part of Letters Patent No. 342,637, dated May 25,1886.

Application filed September 29, 1885. Serial No. 178,548. (No model.)

To aZZ whom it may concern.-

Be it known that I, GEORGE Ross, of Chatham, in the county of Kent,Province of Outario and Dominion of Canada, have invented certain newand useful Improvements in Sulky- Plows, of which the following is afull, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of referenceindicatecorresponding parts in all the figures.

Figure l is a plan View of one'of my improved sulky-plows. Fig. 2 is aside elevation of the same. Fig. 3 is a rear elevation of the sidefurrow-wheel and its connections and showing a part of the frame.

The object of this invention is to provide sulky-plows constructed insuch a manner that one or more plows can be used, and which can readilybe adjusted and controlled.

The invention consists in the construction and combination of variousparts of the sulkyplow, as will be hereinafter fully described andclaimed.

A represents the frame of the machine, which is rectangular in form andmay be of any desired length or breadth.

B are the plow-beams, each of which is formed of two parallel barssecured at their forward and rear parts to coupling-blocks O. Thecoupling-blocks O are slotted from their upper ends to receive the frontand rear end bars of the frame A, and are secured to the said end barsby yokes D and bolts E, so that by loosening the said bolts theplow-beams B can be adjusted laterally, as may be desired. One, two, ormore beams, B, can be used, according as it may be required to use one,two, or more plows.

F are the plows, the standards G of which pass up into the slots of thebeams B, and are secured to the said beams by bolts, rivets, or othersuitable means.

T0 the plow-beams B, in front of the plow.- standards G,are securedblocks H, which have sockets formed through them to receive the shanksof the colters I. The shanks of the colters Iare secured in thesocket-blocksH by wedges J or other suitable means. The forward ends ofthe plow-beams B are inclined downward, as shown in Fig. 2, and have anumber of perforations formed through them, so that the point of draftattachment can be arranged higher or lower, as may berequired.

In case more than one plow-beam be used, the said forward ends of thesaid plow-beams are connected by a bar, K, secured at one end by lugsand a bolt and at the other end by an eye-bar and bolts, so that the barattachments can be adjusted as the desired distance apart of theplow-beams may require. The drawbar K has a number of holes formedthrough it, as shown in Fig. 1, so that the point of the draftattachment can be readily adjusted in line with the center of resistanceto prevent side draft, and thus cause the machine to be drawn forwardsquarely.

Upon the rear part of the near side bar of the frame A and the forwardpart of the off side bar of the said frame are formed or to them arerigidly attached uprights L M, in the outer sides of. which are formedvertical T- grooves, in which are placed slides N 0.

To the slide N is rigidly attached or upon it is formed the axle P ofthe large wheel Q, which travels upon the unplowcd land. Upon theforward edge of the slideN are formed gear-teeth, into which mesh theteeth of the segment R of a gear-wheel placed in a slot in the forwardedge of the upright L and attached to the end of a shaft, S. The shaft Srocks in bearings attached to the side bars of the frame A, and to it isrigidly attached the end of the lever T, which is provided with aspring-lever pawl, U, to engage with the teeth formed upon the convexedge of the arched bar V, secured at its ends to the near side bar ofthe frame A, and thus hold the said lever securely in any position intowhich it may be adjusted.

To the upper and lower ends of the outer side of the forward slide, 0,are attached or upon them are formed lugs V, which are perforated toreceive the upright shaft X.

To the lower end of the shaft X is hinged the axle Y of the small sidefurrow-wheel, Z.

To the inner part of the axle Y is rigidly attached the lower end of thelever a, the upper end of which crosses the curved arm I), rigidlyattached at its inner end to the upper end of the upright shaft X, andserving as a collar to prevent the said shaft from dropping out of thelugs W.

In the arm I) is formed a curved slot, 0, to receive a screw or bolt, d,which passes through it and screws into the lever a, so as to hold thesaid lever securely in any position into which it may be adjusted. Withthis construction, by loosening the screw (1, the lever to can beadjusted to give any desired side pitch to the wheel Z, so that the saidwheel will hold the machine against side draft.

To a support formed upon or attached to the frame Ais pivoted anunequal-armed lever, e, the ends of which are widened and provided withgearteeth, forming segments of gearwheels. The gear-teeth of the shortforward arm of the gear-lever 0 pass through a slot in the rear edge ofthe upright M and mesh into gearteeth formed in the rear edge of theslide 0. The gear teeth of thelong rear arm of the gear-lever e meshinto gear-teeth formed on thelower part of the lever f, which is pivotedto the shaft S, so that by operating the lever f the gear-lever e willbe operated to raise or lower the slide 0 and with it the forward sidewheel, Z.

The leverf is provided with a lever springpawl, g, which engages withthe toothed edge of the catch-plate g, rigidly attached to the 011 endof the shaft S. With this construetion, by operating the lever T, boththe side wheels, Q Z, will be raised or lowered to adjust the plows towork deeper or shallower in the ground or to raise them above theground. With this construction also when the lever T is operated thenear side of the machine will move faster than the off side, the efi'ectof which is to incline the plow-points upward when the plows are raised,and thus cause the said plows to run out of the ground, and to inclinethe plow-points downward when the plows are lowered, and thus cause thesaid plows to enter the ground readily.

When the lever a is operated, the side furrow-wheel Z will be raisedorlowered to cause the plows to out a deeper or shallower furrow or toadjust the machine to travel from place to place.

Upon the rear end of one of the plow-beams B is formed or to it isattached a bracket, h, having a tubular socket at its rear end toreceive the standard 6, the rear end of which is forked, and to it ispivoted the small wheelj, that carries the rear end of the machine.

To the lugs k, formed upon the rear side of the socket-bracket h, ispivoted a lever, I, having a gear-segment formed upon or attached to itsforward end, which enters a slot in the rear side of the socket-bracketh, and engages with annular corrugations upon the standard 7:, so thatthe said standard can be raised and lowered to regulate the pitch of theplows.

The standard 1', when adjusted, is locked in place by a key,m,insertedin a slot in the socketbracket h, and which engages with thecorrugations of the said standard.

To a support attached to the front cross-bar of the frame A is pivotedthe rear end of the plate 11, the forward end of which is provided withupwardly-projecting lugs o to receive the hinging-bolt of the tongue, sothat no down draft from the machine can come upon the horses necks.

To the tilting-lever a of the side furrowwheel Z is rigidly attached therear end of a forwardly-projecting arm,p,to the forward end of which ispi voted the outer end of a connecting-rod, q. The inner end of theconnectingrod q is passed through a lug, r, attached to the lower sideof the forward part of the tongue-plate n, and is secured in place bynuts 3, screwed upon it upon the opposite sides of the said lug 1'.

Upon the rear end of the tongue-plate n is formed or to it is rigidlyattached an arm, t, projecting in the opposite direction from theconnecting-rod q, and to the outer end of which is pivoted the forwardend of the connectingrod u, the rear end of which is perforated toreceive the vertical rod 11. The vertical rod 12 is attachedat its endsto the outer ends of the arms w, the inner ends of which are rigidlyattached to the upper and lower parts of the standard 2, so that thesaid vertical rod will slide through the perforation in the rear end ofthe connecting-rod u as the standard i is moved up and down. \Vith thisconstrue tion, as the tongue is inclined toward one or the other side,the furrow-wheels Zj will be turned in opposite directions, asillustrated in Fig. 1, so that the machine can be turned easily and in asmall space.

Having thus described my invention, what I beams B, of thecoupling-blocks C, the yokes D, and the bolts E, substantially as hereinshown and described, whereby the said plowbeams are firmly secured tothe said frame and can be readily adjusted, as set forth.
